Through research in the blast zone of Mount St. Helens, Evergreen State College scientists have discovered that plants are influencing the ecosystem’s recovery.
A new paper reporting the results, "Plant sex influences terrestrial-aquatic interactions," was published in the journal Ecosphere by Carri LeRoy and her collaborators at the U.S. Forest Service and the Science Museum of Minnesota.
The research, funded by the National Science Foundation, was conducted at Mount St. Helens over the past two summers. It explores how streams in the region are recovering from the 1980 eruption.
The study shows that female willow trees grow closer to streams, contributing organic matter to stream systems. In a carbon- and nutrient-limited environment like a post-eruption landscape, that could affect how these streams function.
